We will be installing a specially designed motor that will require a minumum of 460 VAC at the motor terminals. The motor will be controlled by a Variable Frequency Drive. When calculating the volatge drops due to motor leads, supply cable and VFD losses, we need 525 VAC at the line side input...
What are the advantages/disadvantages/potential problems that need to be addressed when choosing between the following installations? Cost and redundancy need not be addressed.
The installation of a single 4000kVA transformer or two 2000kVA transformers.
